About This Game



I made Gunmetal Orbit because I love Brotato and other bullet-heaven roguelites. I kept the short runs, auto-firing guns and silly builds, then added mining, risky cargo and a space station that fights with you.

FIGHT AND MINE AT THE SAME TIME


  • Your guns fire on their own. You fly, dodge, dash and crack asteroids for ore.
  • Ore is the risk. A fuller hold pays more but slows you down, and getting hit knocks ore loose.
  • Bank it or lose it. Fly it home to your station, or get greedy and stay out for one more load.

BUILD SOMETHING RIDICULOUS


  • Up to six guns at once from 28 weapons: two in your hands and four on mechanical arms. Six SMGs is a real build.
  • Merge matching guns to rank them up, and the top rank lets you pick a wild upgrade.
  • 143 items and 12 pilots, plus fire, ice and lightning effects that combine, until the run gets out of hand.

YOUR STATION FIGHTS TOO


  • Every load of ore you bank charges your station. When it is full, everything you built on it fires at once: a laser strike, a shield, drones that grab loose ore.
  • Build up to four systems over a run and upgrade each one.

A BOSS EVERY FIVE WAVES


  • Four boss machines take turns. One fires mortars, one teleports, one eats the asteroids before you can mine them.
  • Beat one and pick an Artifact, like surviving a killing blow once per run.
  • Runs that fit your time: 10 to 30 waves as you raise the difficulty, a quick Mining Rush, Endless, and a Daily Contract with a Steam leaderboard.

Made for Steam Deck first: controller-first, designed for its 1280x800 screen, with full keyboard and mouse support.

AI Generated Content Disclosure

The developers describe how their game uses AI Generated Content like this:

Some of Gunmetal Orbit's art and audio assets - including concept art used to build 3D models, UI icons, sound effects, and the store page key art - were created during development with the help of generative AI tools, then curated, edited, and integrated by the developers. The store trailer's letterboxed cinematic shots were generated with AI video tools from the game's own art, and its narrator is an AI voice; every full-screen trailer shot is real gameplay. All gameplay code and game design are human-made, and the game does not generate any AI content while you play.
